California is the world's fifth-largest economy, and its security needs are as diverse as the state itself: tech campuses across Silicon Valley, entertainment production in Los Angeles, the twin ports of LA and Long Beach moving 40 percent of the nation's container traffic, Central Valley agriculture, and a retail landscape battling organized theft. No single playbook covers it — coverage has to be built around the site.
Xtreme Security serves California from our North American network, including our Securiwatch office in San Jose. Tech clients get access control, lobby coverage, and parking-structure patrols with a light touch that fits campus culture. Retail and loss-prevention programs target organized retail crime with plainclothes-capable officers and incident documentation that supports prosecution. Logistics sites near the ports get gate coverage, yard patrols, and overnight watch.
Construction is a core strength statewide — from Bay Area towers to Central Valley distribution builds, overnight and weekend coverage with perimeter patrols, gate logs, and shift reports keeps projects on schedule and materials where they belong. Event security covers everything from corporate gatherings to large public events.
Whatever the property, we start with a free on-site risk assessment: a walkthrough, an honest read of exposures, and a post plan with clear scope. Regional clients can run California, Oregon, and Washington sites under one contract and one 24/7 control center. Call 1-800-658-2940 — we answer around the clock.
